山东省芦笋种植面积占全国(20万亩)一半,烟台占全省的一半。近几年,烟台种植的芦笋发生芦笋茎枯病危害十分严重。如乳山县白沙滩乡共种植1800亩芦笋,发病面积就有500多亩,严重地块发病率在60％～70％;福山区的胜利村种植的芦笋一般发病率在30％左右。因病致使植株早衰,茎枝枯死,危害严重,直接影响来年芦笋产量。据日本报道,被此病危害的地区逐步扩大,1981年、1982年胆振管内的西胆振管地区茎枯病率高,受害面积达70％,芦农只能收获往年产量的30％,并且逐年蔓延,危害到其它作物,所以必须引起重视。初感病的成枯茎侧枝上有水渍状病斑,病斑呈梭形,病斑外围是红褐色,中央为灰色,后期病斑上密生黑色分生孢子器,病重时全株布满黑斑,病株相连,围茎一周,造成 Asparagus planting area in Shandong Province accounted for half (20 million mu), Yantai accounted for half of the province. In recent years, asparagus stem blight planted asparagus in Yantai is very serious. As Rushan White Sand Beach Township altogether planted 1,800 acres of asparagus, the incidence of area has 500 acres, the incidence of serious blocks in 60% ~ 70%; Fushan District Shengli village planting asparagus general incidence of about 30%. Premature aging due to disease caused by plant, stems and branches dead, serious harm directly affect the production of asparagus in the coming year. According to reports from Japan, the areas harmed by this disease have been gradually expanded. In 1981 and 1982, the rate of stem blight in the area of ​​gall bladder tube in the gall bladder was high, and the area affected was 70%. The farmers could only harvest 30% of the previous year’s output. Spread, endanger other crops, it must attract attention. The first susceptible into dead stems water stains lesions on the side branches, lesions were fusiform, lesion periphery is reddish brown, the central gray, the late lesion on the dense black conidia, sick whole plant when the whole plant Full of dark spots, diseased plants connected to the perimeter stem, causing
